There are many different types of screws to choose from each with a unique purpose. For example, wood screws that have a spiral thread that helps them grip wood, sheet metal screws that have a sharp point and coarse thread that helps cut through sheet metal, self-tapping screws that cuts into the material as the screw is turned, and eye screws that have a loop at the end just to name a few. With an extensive range of screws available we are sure to have what you need.
